This invention yrel'ers to cotton yarnY ma-l chinery and moreparticularly to an attachment for a spinning machine to produce anauxiliary control otV the motion ot' the spindles .ad bobbins and thethreads or yarns used in connection therew Some or the main obje of thisinvention are to provide an auxiliary bobbin control that willdeiiniteiy' place the bunch on the bobbin in a predetermined positionthereon; that will control thesize or quantity of the bunch according toa` predetermined setting; that will have arrangements .tor adjusting themovement of lthis auX- iliary bobbin control;V that may be attached tostandart spinning trames with facility and without excessive drilling ordisplace,- ment ot parts; that will function definitely with and inconjunction .with other partS of the spinning machine and' the mechanismont the latter; and many other objects that will become apparent as theinvention is more fully set forth. y

n the present types of spinning machines, the winding of the yarn orthread on'thc bobbin producesV a bunchV of thread Or yarn located moreor less indeiinitely; This indefinite location causes difficulties intheoperation of the machineby reason of the breakage that' results andthelumping up oi thread or yarn towards the middleiportion' of the bobbin.In addition wastage occurs on the bobbin by reason of the prematurebreaking or" the thread or yarn, the excessive amount or' thread leifton the bobbin the time, and the various uncertainties that enter intothe situation. Onone bohbin the wastage at one time may be twenty yards,and then again on the next operation the bobbin vin the same positionmay waste double the amount, and so on in consequent opcrationtheamounts may vary preventing any definite predetermination of this waste.is thousands of bobbins may be used in a mill having spinning machineswasting thread and yarn in this manner, the consequent result aiiiects'materially the .cost otoperation and manufacture.

In this invention, the wastage'is reduced, the vamount. or" wastagc ispredetermined and adjusted for, and the general operation of thelspinning machinev is made smoother .and more economical. The' device issimpleein construction and takes up little room on .the machine, andSuch room as it does .-use, vis :in an inconspicuous location where itis out of existing parts ot' the spinning machine;

,In the construction `shown in the drawings, lis a building lever'loffaconventional form of spinning rmachime,-t'vh'ich building leviercontrols the inovem ent of .the thread on the bobbin in accordancewith acam 2 .that is liagrammatic view showing under the operation ofattachedlto the frame vof ,the machine ,and

which Ina-kes Contact with its roller or `ball 3 that is on this flever.yThe general movement of the parts in' the conventional spinning machineis so Well known ,as not .to require further description in detail.vAttached to the lever -1 by the bolt 4 thatvholds theball 3 in place,is the arm 5 of the auxiliary bobbin control, a hole 6 beingprovided inthe ylatter for this bolt to pass through and secure the arm asindicated in the drawings. Theupita) per portion of this arm isprovidedwith a` slot 7 to enable a bolt 8 to :bevertically ad- Vjustaloletherein when vthe. .anni is 'gin ,place, and thus 4make Vitsgear-,segmental kparts .9

come into suitable Contact with apiniOn gear fl() secured on the central`,portion ,Tof `the .cam

9. in a rigid manner so as to operate therewith. This pinion is mountedon a base 11 that is secured to the cam 2 by cap screws 12. The pinionand segmental gear correspond and are designed in sizes to be suitablefor their respective and cooperative functions.

The building lever is of conventional form having suitable counterweightto keep its rear position raised towards the cam surface, and has achain 13 with the segmental arm 14 adapted to be operated in an are andtransmit a vertical movement to t-he bobbin shelf 15 through roller orball 16 and standard 17 in the usual conventional manner.

The raising of the shelf controls the movement with respectto the bobbinand yarn or thread filling on. This filling will vary so that the bunchmay take practically any position on the bobbin, and is erratic becauseof the uncertain relation of the bobbin with respect to the movement ofthe building cam in its conventional action.

lVhen the auxiliary -bobbin control is placed on the machine asindicated in the drawings, its action is such that the segmental gear isbrought into contact with the pinion and indirectly cooperates with thecam 2, at its beginning position and when the building lever is raised.In other words the lever, the earn, and the auxiliary bobbin control areset at a certain positionwhich corresponds to the starting of the bobbinfilling process. The segmental gear being in contact serves to keep thecam and its roller or ball out of contact until the number of teeth onthe segmental gear in use are run off. During this run-off the thread oryarn makes the bunch on the bobbin and at the lower end of the bobbin.The amount of the bunch is determined by the movement of the segmentalgear, which in turn through tne other mechanism of the spinning machineinfluences the filling process. After the segmental gear has completedits arc stroke, it progresses until the indentation is reached, at whichpoint the indentation 45 moves up against the pinion gear and allows thebuilding lever and the arm 5 to rise also. As the building lever risesunder the action of gravity on its counterweight, the ball 3 makescontact with the cam 2 and for the rest of the filling process theregular action of the spinning machine takes place.

When the bobbin is filled it is removed and another put in its place,the bobbin shelf is moved through a special mechanism operated by t`hefoot, and the building lever is so depressed that In Figure 2, thebobbin is indicated at 19 with the yarn shown at 20 and the bunch at 21near the bottom.

That the segmental gearis lowered out of its indentation portion fromcontact with the pinion. The segmental gear is overweighted on theportion 46 that helps to ess of the bobbin.

The adjustable stop 47 has a series of positions 18 to provide for acontrol of the arc of movement of the segmental gear, thus enabling thebunching process to be made small or large as the case may need.

The construction of this segmental gear is such that its gear teeth maybe interchangeably positioned against the pinion gear, the manner ofdoing so being by replacing this portion of the control after reversingthe segmental gear faces. This feature permits a quick change in case ofan urgent need of an emergency gear on the segment. The two segments areprovided with means for attaching the overweight and for adjustabilityof movement.

It should be noted that the only constructional change in theconventional form of spinning machine required, is the drilling ef twosmall holes for attaching the pinion gear to the cam, a matter of littledifHculty, and` which does not affect the spinning machine in any way incase they should not be utilized at any time.

While but one form of the invention is shown in the drawings it is notdesired to limit this application for patent to that particular form orin any way, than limited by the prior art, as other forms could be madethat would use the same principles and come within th-e scope of theappended claim.

I-Iaving thus described the invention, what is claimed is:

An auxiliary control comprising in combination, an arm attachable to thebuilding lever of a spinning machine, a double segmental member movableon the upper portion of the arm having means for adjustably positioningit on the arm and its movement thereon, one of said segmental partshaving gear thereon, and another portion weighted to normally positionthe whole member in a predetermined position, a gear moveable with thecam mechanism of the spinning machine, adapted to engage with segmentalgear portion, and during such engagement to directly disengage the sai-dlever from the cam mechanism, until a certain period of the spinning hastranspired.

In testimony whereof I hereunto affix my signature.

PHILIP S. GIROUX.
